You can do it yourself with the proper tool. I think it's called an angle finder. It measures the angle of the driveshaft or any angle you want to measure. I believe the angle at the transmission and the angle at the rear end must be the same. There may be an acceptable amount of difference between the two, but I'm not sure. I am no expert in this field so you may want to check with an expert or at least someone who can give you more definite answers. You also have to make sure that the driveshaft doesn't bind at full suspension droop due to lack of clearance for the u-joints.

awesome... looks like i should be able to get the kit in about 2 weeks and a twelve pack and have some fun.

you should be ok

pinion angle is the total angle of the trans yoke and the rear yoke. I believe that is correct.

You can do a search but I think that is correct from setting the pinion angle on my mustang. Which was set to like -3 or -4 so that when I launch the car it should come up to 0.

level or lift?
 

i want to put 33x12.50 tires on my 05 f150 4x4. can i get away with just a leveling kit or do i need to lift the whole thing?

im in the same boat as u i did mine its a 2.5 super lift i broke a cv boot putting it on and i just replaced that myself but i messed up my ball joints i think or somethign idk if i take it back to the dealer what theyd say cuz i didnt go there for my 35k tune up i did it myself

i dont think u even ned to level it i had 32s on my stock and i put the leveling kit on looks like i can fit 35s

Doing a leveling kit should not void your warranty. Unfortunately it is up to the individual dealership as to whether they want to cover it.

Rainman, you will be able to clear 33x12.50 by doing a 2.5" leveling kit. You may be able to put 33x12.50s on at the stock height but they will rub while turning and/or flexing.

i just bought an 08 f150 fx2 i only have 5k miles on it and i just put a djm lowering kit 3.5 in front 5.0 in rear ive taken it in 2 times for tranny problems before putting in the lowering kit,now i have a tranny leak and tomorow im taking it in the ford dealer with the lowering kit install.now i talked to a friend at another ford dealer and he said a lowering kit will not void your warranty unless you have a problem that the lowering kit developed but since the lowering in basically suspension it would void you suspension warranty ,but some lowering kit do need driveshaft angle adjustments or it will cause a vibration
